The number of employees hired by colleges and universities to manage or administer people, programs and regulations increased 50% faster than the number of instructors between 2001 and 2011, the U.S. Department of Education says. It’s part of the reason that tuition, according to the Bureau of Labor Statistics, has risen even faster than health-care costs.
